I temporarily moved my PCI Delta 1010 card into a PCIe slot, via a

mechanically. For one, the S/PDIF connectors end up covered up by

But, all the xruns are now gone. That would tend to support the
theory that this is an interrupt crowding issue. ;-)
On this board I have no freedom to change the interrupt assignment.
The video card I have now takes two slots worth of space, though it
only plugs into one slot. That means that I can't move it to a
better location. I might buy a smaller video card to get around
that. How much GPU do I need for Linux audio after all?
My next experiment will be to try the CCRMA rtirq stuff to see if
changing the kernel servicing of interrupts will get me good enough
performance that I can just leave the hardware where it was.
